SignalK node server plugin that reads data from bmp180 temperature/barometer sensors on Raspberry-Pi
npm install signalk-raspberry-pi-bmp180This plugin can be downloaded via the SignalK application.
This plugin has been inspired by the plugin "signalk-raspberry-pi-bme280" developped by Jeremy Carter.

You need to make sure Raspberry Pi is turned off while doing this!
In order to use the sensor, the i2c bus must be enabled on your rasbperry pi. This can be accomplished using "sudo raspi-config".
If the sensor isn't found you can run ls /dev/i2c which should return /dev/i2c-1. If it doesnt return then make sure that the i2c bus is enabled using raspi-config.
You can also download the i2c-tools by running sudo apt-get install -y i2c-tools. Once those are installed you can run i2cdetect -y 1. You should see the bmp180 detected as address 0x77. If the sensor isn't detected then go back and check the sensor wiring.
